The left and right support columns 60 and 60 and the left and right support columns 62 and 62 are connected by the left and right cylinders 61 and 61.

  The root vegetable harvesting machine according to the present embodiment pulls out the carrot X from the field, conveys it backwards, cuts the foliage and harvests the root of the carrot X, and the carrot X dropped from the rear of the harvesting part C. The first transport part D (residual leaf processing device) that transports the remaining leaves of the machine to the other left and right sides of the machine body, and the carrot X that is transported from the first transport part D by the transport conveyor to the rear part of the machine body A second transport unit E for transport is provided.

  Therefore, the machine body is configured such that the crop harvested from the field by the harvesting unit C is transported to the other side of the machine body by the first transport unit D and transported to the accommodation bag 63 at the rear of the machine body by the second transport unit E. Since the transport distance in the left-right direction is shortened, the left-right width of the aircraft can be made compact, turning performance is improved, and loading into a light truck or the like is facilitated. Moreover, since the 2nd conveyance part E can move up and down, since the fall distance of a crop can be made small by changing height according to the accommodation amount of the crop in the accommodation bag 63, a crop has fallen. As well as being able to prevent damage from impact, the front-rear width of the airframe can be made compact, so that the turning performance is improved and loading into a light truck or the like is facilitated.

  4 is a left side view of a modified example of the root vegetable harvester shown in FIG. 1, and FIG. 5 is a plan view of the root vegetable harvester shown in FIG. The frame 64a, the slide base 64b, and the guard member 64c may be configured such that the slide base 64b slides rearward and then rotates near the rear end portion of the roller wheel 65 so as to be inclined downward.

  The rotation fulcrum 64b1 inclined downward of the slide base 64b provided at the rear end portion of the containing bag receiving frame 64a is provided so as to be positioned above the rear end portion of the wheel 65, thereby interfering with the wheel 65. The slide base 64b can be rotated.

  In addition, by providing a guard member 64c on the upper part of the slide base 64b to support the lower portions of both sides of the storage bag 63 so that the storage bag 63 does not slide down on both sides, the slide base 64b slides backward together with the guard member 64c. The storage bag 63 can be lowered to the ground at a gentle angle by tilting downward, removing the storage bag 63 from the left and right suspension arms 58 and 58, and moving the machine forward.

  Further, since the slide base 64b is configured to be detachable from the storage bag receiving frame 64a, the slide base 64b can be exchanged according to the size of the storage bag 63. Furthermore, by arranging the terminal end side of the containing bag receiving frame 64a so as not to protrude rearward from the wheel 65, the front-rear width of the machine body can be made compact.

  As described above, the slide table 64b on which the storage bag 63 is mounted is movable in the longitudinal direction of the machine body, so that the position of the slide table 64b is stored in the storage bag 63, and the crop is fully loaded. Since the storage bag 63 can be switched to a discharge position for discharging the storage bag 63 to the outside of the machine, it is easy to store the crop and discharge the storage bag 63 from the machine body, thereby improving work efficiency.

  Moreover, even if the weight of the crop accommodated in the storage bag 63 on the bucket 64 is increased by providing the wheel 65 within the front and rear width of the storage bag receiving frame 64a and at the bottom thereof, the wheel 65 is grounded. Since the bucket 64 is supported, it is possible to prevent the weight from being excessively applied to the bucket 64 and destroying the weight balance, so that the traveling posture of the machine body and the harvesting posture of the crop are stabilized.

Further, as shown in FIG. 4, since the cylinder 61 is supported by the storage bag receiving frame 64a and the guard member 64c via the support column 60 and the like, the configuration near the placement portion of the storage bag 63 can be made compact.
Also, a pair of cylinders 61 is usually provided on both sides of the storage bag receiving frame 64a. However, if it is provided only on one side of the storage bag receiving frame 64a on the opposite side of the auxiliary worker sitting on the seat 54, the work is not performed. Does not get in the way.

  Furthermore, the slide base 64b, the storage bag receiving frame 64a, and the guard member 64c are foldable in the direction of arrow A in the enlarged view of the bucket 64 portion of FIG. 4 shown in FIG. 4 or FIG. It can be stored and becomes compact when transporting the harvester.

The left side view of the harvesting machine of the bucket 64 portion of FIG. 7 shows a configuration example in which the rear portion of the slide base 64b is inclined downwardly so as to be curved above the wheel 65.
In the configuration shown in FIG. 7, a plate 64d is slidably disposed on the upper side of the containing bag receiving frame 64a, and rods 64dd having protrusions on both sides of the plate 64d are provided in a space provided inside the slide base 64b. When the storage bag 63 is inserted and lowered onto the ground, the storage bag 63 is slid by allowing the plate 64d in contact with the bottom surface of the storage bag 63 to slide down on the slide table 64b via the rod 64dd. The top 64b slides smoothly along with the guard member 64c.

  In this example, the slide base 64b is configured to be fixed to the storage bag receiving frame 64a that does not slide. In this case, when the storage bag 63 is lowered onto the ground, the distance between the storage bag 63 that starts to be lowered and the ground is shortened. The carrot X stored in the storage bag 63 is prevented from being impacted, and the storage bag 63 can be discharged out of the apparatus without damaging the carrot X. In particular, it is easy to prevent the carrot X from being damaged at the bottom of the accommodation bag 63.

  Further, as shown in FIG. 1, the horizontal distance L1 from the clamping start end of the left and right clamping conveyor belts 19 and 19 of the harvesting section C to the rear of the alignment devices 34 and 34 is the horizontal length L2 of the bucket 64. Since the storage bag 63 is lowered from the bucket 64 to the field or the like before the left and right nipping and conveying belts 19 and 19 pull out and convey the carrot X from the field and cut the foliage, the storage bag is continued while the harvesting operation is continued. 63 can be exchanged, and work efficiency is improved.

  Further, as shown in the side view of the harvester near the bucket 64 in FIG. 8, an inclined plate 71 is provided between the left and right arms 56, 56. The inclined plate 71 made of an elastic body moves up and down in conjunction with the up-and-down movement on the end side of the conveyor 50, and descends when the amount of the carrot X stored in the storage bag 63 is small at the start of harvesting or the like. Since the carrot X is received in the storage bag 63 upon receiving the carrot X falling from the terminal end of the transport conveyor 50 in the state, the distance of the carrot X is shortened, and the carrot X is prevented from being damaged by the impact of the drop. be able to. Further, when the harvesting operation proceeds and the capacity of the carrot X in the accommodation bag 63 reaches the accommodation limit, the inclined plate 71 is discharged from the end portion of the transport conveyor 50 in the raised state and is collected on the front side of the machine body of the accommodation bag 63. Can be held down to some extent so that the carrot X can be spilled out of the storage bag 63, so that the operator can carry out the harvesting work of the carrot X up to the limit of the capacity of the storage bag 63. The capacity of one bag is increased and work efficiency is improved.

Since the suspension arm 58 is supported by the arm 56 via the connecting rod 57, the arm 56 is disposed so as to be pivotable in the vertical direction, and the suspension arm 58 is moved upward when the accommodation bag 63 is discharged. As a result, the suspending arm 58 does not obstruct the discharge of the storage bag 63, and the workability is improved.
Further, since the suspension arm 58 and the inclined plate 71 are configured to be above the upper surface of the storage bag 63 on the bucket 64 when the sorting conveyor 50 is positioned above, the storage bag 63 with the upper surface opened. It becomes easier for crops to enter from the sorting conveyor 50.

  In addition, by adopting a configuration in which the inclined plate 71 is locked between the left and right of the hanger hook-shaped left and right arms 56, 56, a support member to which the inclined plate 71 is attached can be omitted. Cost reduction can be achieved.

  Further, as shown in the side view of the harvesting machine near the bucket 64 in FIG. 9, the shooter 72 for preventing the cracking of the harvested product is supported in the storage bag 63 by the arms 73 on the left and right cover frames 46, 46 of the sorting conveyor 50. Installed and moved up and down. The shooter 72 was manually rotatable around the base of the arm 73 connected to the left and right cover frames 46, 46. It is desirable for the auxiliary worker near the bucket 64 to rotate the shuter 72 while watching how the harvest is carried into the storage bag 63 so that the crop can be prevented from cracking.

  Further, in the side view of the harvesting machine near the bucket 64 in FIG. 10, the first shooter 72 a for preventing cracking of the harvested product is provided in the storage bag 63 between the left and right cover frames 46, 46 of the sorting conveyor 50. Attached to the end of the bent first arm 73a, the base of the second arm 73b is attached to the first arm 73a, and a second shooter 72b is provided at the end of the second arm 73b to allow vertical movement. An example is shown. The first arm 73a connected to the left and right cover frames 46, 46 and the second arm 73b attached to the first arm 73a are attached so as to be manually rotatable around the base. The first arm 73a is preferably rotated while an auxiliary worker in the vicinity of the bucket 64 looks at how the harvest is carried into the storage bag 63 so that the harvest can be prevented from cracking.

  As shown in FIG. 10, the rotation fulcrum position of the first arm 73a is provided on the left and right cover frames 46, 46 of the sorting conveyor 50 behind the end of the sorting conveyor 50, and the base of the second arm 73b is provided on the first arm 73a. The first shooter 72a is attached to the end of the first arm 73a, and the second shooter 72b is attached to the end of the second arm 73b. After being received by the first shooter 72a and further received by the second shooter 72b and dropped downward, the fall distance of the carrot X can be made very short, so that the carrot X can be prevented from being damaged by the impact of the drop. The product value of carrot X can be improved.

  Also, if the left and right widths of the first shooter 72a and the second shooter 72b are substantially the same width as the left and right width of the transport conveyor 50, the carrot X can be received and dropped without giving an impact as much as possible. There is no need to use it, and it is possible to reduce the cost and weight of the aircraft. Further, since the left and right widths of the first shooter 72 a and the second shooter 72 b are narrower than the left and right width of the storage bag 63, the first shooter 72 a and the second shooter 72 b do not interfere with the storage of the carrot X, and the storage bag 63. The carrot X can be stored up to the limit of the storage capacity.

  In addition, the shooter 73c provided at the front end of the support frame 46 of the sorting conveyor 50 drops directly below the carrot X without contacting the shooter 72, the first shooter 72a, or the second shooter 72b from the terminal end of the transfer conveyor 50. In addition, the carrot X is prevented from being damaged by impact.

  Further, as shown in FIG. 10, the first shooter 72a and the second shooter 72b are manually rotated with the rotation center of the first arm 73a supported rotatably at the tip of the support frame 46 of the sorting conveyor 50 as a fulcrum. It may be configured to be movable.

  As shown in the plan view of the main part near the bucket 46 in FIG. 11, an accommodation bag receiving frame 64a and a slide base 64b are arranged behind the crawlers 1L and 1R (side view), as shown in the rear view of the machine body in FIG. The storage bag receiving frame 64a, the slide base 64b, and the guard member 64c are inclined to the side of the machine body. Since the storage bag 63 is located behind the machine body, the guard member 64c mounted on the slide table 64b can be inclined toward the outside of the machine body by sliding the slide table 64b to the left and right outside of the machine body. The bucket 64 composed of the frame 64a, the slide base 64b, and the guard member 64c is inclined.

Further, since the bucket 64 is inclined in the left-right facing direction of the harvesting portion C with respect to the longitudinal center line of the aircraft in plan view, the storage bag 63 can be discharged to the side where the carrot X has been dug. Therefore, there is no hindrance to the harvesting work in the next process. Further, since the rotation fulcrum 64b1 of the slide base 64b constituting the bucket 64 is provided above the outer side of the machine body from the wheel 65 in the rear view of the machine body, there is an advantage that the bucket 64 does not interfere with the wheel 65.
Furthermore, since the storage bag 63 can be lowered while running the aircraft in either the forward or reverse direction, the lowered storage bag 63 does not interfere with the crop harvesting operation in the next step.

  Further, since the pivot point 64b1 of the slide base 64b toward the side of the machine body is located outside the center of gravity of the storage bag 63 in the rear view of the machine body, the slide base 64b and the guard member 64c are provided when the harvested product is carried into the storage bag 63. Is not applied to the cylinder 64e connected to the guard member 64c.

  As shown in FIGS. 5 and 11, the shape of the bucket 64 is not provided with a guard 64 c on one side of the bucket 64, so that it does not hinder the storage bag 63 from being lowered.

  As shown in the rear view of the vicinity of the bucket 64 of the harvesting machine in FIG. 13 and the plan view of the vicinity of the bucket 64 of the harvesting machine in FIG. 14, the rolling wheel 65 can also be provided behind the bucket 64 via a frame 75. In this case, since the rotation fulcrum 64b1 of the slide base 64b of the bucket 64 can be provided on the inner side of the body of the bucket 64, the bucket 64 can be gently inclined so as to be in contact with the ground.

  As shown in the plan view of the vicinity of the bucket 64 in FIG. 15, the container bag receiving frame 64 a is rotated horizontally and obliquely rearward about the rotation fulcrum 64 aa provided in the vicinity of the front side corner portion. The bucket 64 may be tilted rearward at a spaced position, and the accommodation bag 63 may be discharged obliquely rearward. In this case, the left and right balance can be improved as much as possible and the work of the next process can be prevented from being obstructed.

  The storage bag receiving frame 64a is configured to rotate integrally with the reinforcing support rod 76 passing through the rotation fulcrum 64aa, and the rotation of the storage bag receiving frame 64a is driven by a motor (not shown) as a power source. A limit switch 77 is inserted at the end of rotation of the storage bag receiving frame 64a, and the storage bag receiving frame 64a is inclined toward the ground so that the storage bag 63 can be lowered to the ground.

  Further, a rotation lock mechanism 76a for the storage bag receiving frame 64a is provided at the end of the support rod 76 so that a signal for tilting the storage bag receiving frame 64a toward the ground is not input while the rotation lock mechanism 76a is operating. To ensure safety. The lock mechanism 76a is arranged on the side of the work assistant's seat 54 so that the work assistant can easily work.

FIG. 16A is a side view of the conveyor 50, FIG. 16B is a plan view, and FIG. 16C is a side sectional view of the lug 50a of the conveyor 50.
The lug 50a attached to the belt of the conveyor 50 has a flat shape formed by combining a circular portion (loop-shaped portion) formed by bending a plate material at the center in a side sectional view and a lower base portion thereof. Such a lug 50a prevents the carrot X from falling by the circular cross section, enhances the transportability of the carrot X by the conveyor belt, and eliminates the carrot X from entering the space in the circular cross section. Moreover, even if the carrot X hits the circular section (loop-shaped section), the harvested product does not break because it is soft.

  As shown in the plan view of FIG. 16 (b), a plurality of lugs 50a are provided in the moving direction of the belt of the conveyor 50, but the lugs at each stage are created as an integrated object, thereby reducing costs. Further, since the lugs 50a of each stage are provided with a plurality of notches 50aa at a predetermined interval, mud flows through the notches 50aa and does not accumulate on the belt.

As shown in the plan view of FIG. 17 (a) and the side view of FIG. 17 (b), when the conveyor 50 is composed of a plurality of rollers 50b, a resistor 50c is installed below the operating portion of the conveyor 50. In the configuration in which the harvested product is rotated on the roller 50b, since the harvested product is brought closer to the seat 54 side of the sorter (auxiliary worker) by making the roller 50b conical, the sorting operation is easy.
When the diameter on the seat 54 side of the conical roller 50b is L3 and the diameter on the opposite side is L4, L4> L3 makes it easy to sort because the harvested product is on the sorter side.
Moreover, since the roller 50b is made of a soft material such as rubber, the harvested product is not broken and the resistance is increased, so that the harvested product tends to approach the sorter side.

As shown in the plan view of FIG. 18 (a) and the side view of FIG. 18 (b), the conveyor 50 is composed of a plurality of rollers 50b ′, and a wide belt 50d is disposed below each roller 50b ′. By bringing the conveying direction of the wide belt 50d in the direction perpendicular to the conveying direction of the plurality of rollers 50b ′ to the direction in which the seat 54 of the auxiliary worker (sorter) is located, the harvest is brought to the sorter side. Therefore, sorting is easy.
At this time, the pitch L5 of the rollers 50b ′ of the conveyor 50 is set to be larger than the maximum diameter of the harvested product, so that the harvested product is surely brought into contact with the wide belt 50d and brought to the sorter side.

  According to the present invention, the root crop harvester has industrial applicability as an agricultural machine that frees workers from heavy labor.
